Bar grating is good choice for strength, safety, long-term cost and durability. Bar Grating consists of a series of bearing bars, welded (or otherwise joined) at various intervals to perpendicular cross bars to form a load-bearing panel. Stock Panels are manufactured by a process called electrofusion welding. Our typical panel configuration has bearing bars with perpendicular cross bars and a 3/16″ thick piece of flat bar around the edge of the panel to create additional strength during loads. Welded Construction: 3/4″ x 3/16″ Bearing Bars, 1-1/2″ on Center, Regular Cross Bars 4″ on Center. Other spacings are available to meet your loading and open area requirements. Our Steel Welded Bar Grating is available in a Hot-Dip Galvanized, Black Painted or Carbon Steel, Smooth finish.
